Mikel Merino was Arsenal’s hero coming off the bench to play as an emergency striker and scoring twice in the final 10 minutes.

The Gunners, however, got the win they needed as Merino struck twice in the final 10 minutes.
Arsenal closed the gap on Premier League leaders Liverpool to four points by beating Leicester.
